Answer 1

Answer:

Step-by-step explanation:

99% of the work is just finding the right formula (and doing some dimensional analysis to make sure you didn’t google up the wrong tree).

Centripetal acceleration is given by[1]

$a_{c}$=$v_{t} ^{2}$/r,  

where $v_{t}$ is the velocity tangent to the circle in m/s,  and r  is the radius of the circle in m.  

So we know $a_{c}$ an $v_{t}$,  and we just need to find r.  

10=$5^{2}$/r,  

so    r=5/2 m.
